The word "NEOFFI" can be a bit confounding when it comes to spelling. It is actually a made-up word, but its pronunciation can be explained using the International Phonetic Alphabet (IPA). The first syllable "neo" is pronounced as "niːəʊ", with a long "ee" sound and a schwa sound at the end. The second syllable "ffi" is pronounced as "fiː", with a long "ee" sound. Therefore, the correct spelling of the word would be "NEOFFEE" if it were a real word.
